I spend on average 4 hours every two days in front of the computer ,I also use quite a msg with the cell phone is very important in communication as well, is to address issues of work or study!
I believe that parents should have more attention on children who are long in front of the computer,It can cause a number of diseases is always good to know everything that happens in the virtual world, the more we should not forget to do physical activities or just forget the world outside!
Ai's a suggestion people who occupy most of the time in front of the computer, change your routine, find another hobby, decrease the time on the computer, try to make something healthier and have a long and happy life!
